Answer:

the federal government

Explanation:

The National Meteorological Service is an agency of the federal government. For this reason, we can say that the scientists who work at this agency and provide meteorological data, which the reporters trust to inform the weather forecasts, are hired by the federal government.

These agencies do not have the sole function of reporting the weather forecast in the country, but also have a responsibility to inform when there is a dangerous weather forecast that can endanger the lives and integrity of citizens and the country.

Charcoal is primarily carbon. what mass of co2 is produced if you burn enough carbon (in the form of charcoal) to produce 4.80 k
Reika [66]
When carbon is burned in air carbon iv oxide gas is formed.
C (s) + O2 (g) = CO2(g)  ΔH = - 393.5 kj/mol
The enthalpy change of the  reaction is -393.5 j/mol which means that when one mole of carbon is completely burnt in air then 393.5 j of energy is evolved.
Thus, 1 mole = -393.5 j , then for 480 kj 
            = 480 × 1/393.5
             = 1.2198 moles
          1 mole of carbon iv oxide is equal to 44 g 
thus, 1.2198 moles will be 1.2198 × 44 = 53.6712 g of CO2

1. Que factores provocan la oxidación?
Katyanochek1 [597]

Answer:

Mira la explicación.

Explanation:

Hola,

Las reacciones de oxidación se definen como aquellos procesos químicos en las cuales uno de los elementos involucrados sufre un aumento en su estado de oxidación, causado por el efecto de un agente oxidante, el cual es capaz de aceptar los electrones perdidos por dicho elemento oxidante. Dentro de los factores promotores de la oxidación se pueden encontrar:

1. Presencia de oxígeno gaseoso: al ser un agente oxidante fuerte, es capaz de recibir electrones de casi cualquier sustancia.

2. Presencia de humedad: a la larga, cuando una sustancia reacciona con agua tiende oxidarse ya que el agua posee oxígeno y como se vio anteriormente, es el principal promotor de oxidación.

3. La presencia de algunas sales iónicas como cloruro de sodio también promueven la oxidación, por ello es que no debemos introducir joyería al mar, debido a que esta salinidad induce reacciones electroquímicas que son capaces de oxidar metales.

4. Reacciones con ácidos oxidantes: ácidos como el nítrico, son oxidantes fuertes que tienen la capacidad de disolver metales (oxidarlos) y formar nitratos, por ejemplo el cobre en presencia de ácido nítrico, sufre una oxidación bastante violenta.

Saludos!

I
Bond [772]

Answer:

about 0.7 g/mL

Explanation:

Density = mass ÷ volume

D = 5.29 g / (12.6 mL - 5.00 mL)

D = 5.29 g / 7.6 mL

D = 0.696052.... g/mL

D = about 0.7 g/mL
